It looks like a valve keeper to me. You must have a sticking valve or you over reved the engine. You may have a broken valve spring.Bare

You can't over-rev one - the rev limiter is at 5400rpm's or so ..... and if it would have dropped a keeper out - it would have dropped the valve .... such is the design of the keepers and valve stem .....
